"He's on a downward spiral that is very, very dangerous," Silver said. "I just want to put this in perspective ... I was with a Browns player yesterday. Johnny Manziel, going into what would be a start late in the season showed up drunk at practice on a Wednesday. The Browns lied and said he was in the concussion protocol. Let me say that again, the Browns lied. To try to protect and I would argue, enable this irresponsible and very troubled young man."

As The Big Lead points out, the incident lends credibility from a previous report by Tony Grossi that Manziel showed up 'inebriated' to practice and was sent home prior to the team's season finale, which could explain his absence from the stadium for evaluation under the concussion protocol.

Silver went on to explain that he does not believe that there is a coach in the NFL that would hitch his wagon to Manziel and any speculation about his future in the league is irresponsible given how he has carried himself off the field and his lackluster performance on it.

This has been a tumultuous year for Manziel who was spotted in Las Vegas partying while wearing a wig as a disguise after previously spending time in an alcohol treatment facility and Monday details surfaced from an alleged domestic violence incident in which is ex-girlfriend claims she was slapped so hard by Manziel that her eardrum ruptured. Police searched for Manziel using a helicopter following the incident.

The Browns are likely to release Manziel sometime between now and the league year beginning on March 9 and the organization has been given plenty of justification to do so based on his off the field conduct since being selected in the first round of the of the 2014 NFL Draft.
